AD9148 VDD power consumption

In the AD9148 datasheet there is the list of all VDD connections (AVDD33, CVDD18, IOVDD and DVDD18) with a typical and a maximal value.

Is the maximal value the absolute maximum power consumption of the supplies or is this in a specific context ?

    The maximimum power consumption is for the particular mode specified

     

    (NCO OFF, PLL DISABLED, AND INV SINC

    FILTER BYPASSED, 8 × Mode, f DAC = 800 MSPS, f INTERFACE = 200 MSPS

     

    The part can dissipate much higher power with NCO on and Inv Sinc on. You may need to add a heat sink

    if you try to use NCO and INVsinc at max data rate.
